Updated Project Risks
● FieldTex and NexoTherm collaborations● Possibility of packaging, sewing and manufacturing the garments
ourselves ● Research on additional vendors
![Page 9: Body Cooling System - Rochester Institute of Technologyedge.rit.edu/edge/P16013/public/Detailed Design Documents/Review I… · Estimated Net Income $3,167.82 $3,723.38 555.56](https://reader031.vdocument.in/reader031/viewer/2022030422/5aa97c377f8b9a95188ce2b2/html5/thumbnails/9.jpg)
Materials Consideration● Inside layer: moisture management
○ Goal: move perspiration away from the body○ Material that will wick moisture away from skin○ Solution: synthetic fabrics
● Outside layer: insulative and lightweight○ Goal: trap air to maintain insulation of cooling packs○ Solution: Natural fibers or classic fleece○ Synthetics including Thinsulate
● Continuing research on materials for both applications and working with FieldTex on initial materials so that they can be tested

FieldTex Collaboration● Local manufacturer of soft-sided cases (bags, vests, straps, etc.) for
military and medical applications● Capacity to manufacture short runs or large quantities
○ Designers and over 85 sewing machines in house
● All three prototypes can be easily made - will initially focus on belt● FieldTex will provide proposal and prototyping quote● Materials available in house for prototyping
○ Velcro compatible material for outside○ Multiple material ideas for inside (lycra, mesh, heating pad slip cover material)
